[nos-bbs] status of MID/BID comparison

O.K.  I'm just trying to make sure I understand the prevailing school of thought.

In the case we saw locally, it appears that if JNOS consistently used UPPER case, then the problem would most likely have been avoided at the BPQ system.  That doesn't eliminate the problem, but it makes it less likely to occur.

I'll talk to the BPQ owner and let him know what I've heard.  Perhaps he can convince the BPQ developer to no use case sensitive comparisons (or perhaps make it a configurable option so sysops can turn it off if they're having problems).

Thanks all (and especially Maiko - as usual!)
